1. (6 pts) Provide two different syntheses for 1,1-diphenyl-1-butanol starting from a carbonyl compound and using a Grignard reagent. Synthetic Route 1: carbonyl Grignard reagent a) THE b) H30* work up 1,1-diphenyl-1-butanol Synthetic Route 2: carbonyl Grignard reagent a) THF b) H30* work up ОН 1.1-diphenyl-1-butanol 2. (3 pts) The use of Grignard reagents requires scrupulously dry aprotic solvents such as diethyl ether or tetrahydrofuran. Please explain why the solvents need to be scrupulously dry. To support your reason, show...
